Dataset: Aggregate Sinking Velocity from the CO2 Aggregation Experiment from UCSB Marine Science Institute Passow Lab from 2009 to 2010 (OA - Ocean Acidification and Aggregation project)

Series 2: CO2 Aggregation Experiment - Aggregate Sinking Velocity

The sinking velocities of ten randomly selected aggregates from each tank were measured
in a 2-liter cylindrical settling column that was 8 cm wide in a temperature constant room . Each
aggregate was allowed to sink out of the wide bore pipette into the settling column. The duration
of the descent of the aggregate over a distance of 20 cm, from 6 cm below the surface to 6 cm
above the bottom, was monitored using a stop watch. Just before this, the length and width of
each aggregate were measured to the nearest mm under a dissecting scope. Aggregate volume
was calculated based on an ellipsoid shape, assuming that width and depth were identical.
